Question

Problem L:(4 points) lel wires are placed side-by-side and they carry equal but opposite aurents. From your point of view, the wire on your right carries the current toward you, and the wire on your left carries the current away from you. What is the net magnetic feld at a point exactly midway between the two wires from your point of view. a: points up. a: points down. a: is zero. o: points toward you. Problem 2: (4 points) Which of the statements below can be attributed to Ampere's law? o: The net magnetic field around a closed loop depends on currents passing through it. o: There are no magnetic monopoles. o: The net electrical field over any closed surface depends on the enclosed charges. a: A changing magnetic field induces an electric field. Problem 3: (4 points) A conducting loop moves to the right and leaves a region of constant magnetic field pointing out of the page perpendicular to the loop. While entering, the motional enf ?: will be zero. ?: induces a counterclockwise current in the loop. o: induces an upward current. o: induces a clockwise current in the loop. Problem 4: (4 points) A beam of light leaves a transparent material and enters vacuum at an oblique angle. Leaving the material, the light beam will a:.continue to travel in the same direction. o: be completely reflected. a: bend toward the surface normal. a: bend away from the surface normal. Problem 5: (4 points) Images formed by a concave mirror are a: always enlarged o: always farther from the mirror than the focus point. o: always real. o: none of the above.

Explanation / Answer

1. Using right hand thumb rule

Net magnetic field points downward.

---------

2

Option(a) is correct.

-----

3. Using Lens law, it induces clockwise Current.

-----

4. As the light ray pass through a denser to rarer so it bend away from the normal.

----

5.

Images formed by concave mirror is either real or virtual.

So, none of the above is correct.

Do comment in case any doubt.. good luck
